BRINE COOLER Filed April 22, 1926 I5 I? I Charles Moore 29 l O Q Patented June 10, 1930 UNITED STATES. PATENT OFFICE CHARLES A. MOORE, F EDINA, MINNESOTA BRINE COOLER Application filed April 22, 1926. Serial No. 103,778.

My invention relates to improvements in gated tank indicated in its entirety by the refbrine coolers for use in connection with reerence character A. This tank comprises a frigerating appliances embodying circulat botton'i- 10, sidewalls 11 and 12, endwalls l3 ing brine as the refrigerating medium. and 14 and a cover 15, which parts may be 5 In many of the conventional refrigerating constructed in any approved manner provid- 55. appliances, systems of pipes for brine are eming for the effective insulation of the contents ployed, said pipes being connected in a cir-' of the tank. The usual refrigerating systems cuit including a pump for forcing the brine or appliances with which my improved coolthrough said pipes and also including a coolor is adapted to be used includes a brine feed er tank for thebrine, said tank containing main and a brine return main, the former 60 coils for ammonia or other refrigerant servhaving a pump (not shown) incorporated ing to reduce the temperature of the brine in therein. Such brine feed and return mains its passage through the cooler tank. are respectively indicated by the reference It is to such cooler tanks that my invention numerals l6 and 17. The brine feed main particularly pertains, one object of the in- 16 is fitted at its receiving end in aflange cou- 65 vention being to provide a brine cooler, pling 18 bolted to the end wall 13 of the tank wherein the terminals of the brine feed and A. Within said tank, I provide a brine feed return mains are constructed and arranged terminal consisting of a pipe 19, one end in a manner causing the effective reduction in thereof passing through said endwall 13 and 20 temperature of the circulating brine, whereby threaded into said flange coupling 18, the 7 a stimulated flow of the brine through a reother end of said pipe being closed by means frigerating appliance maybe accommodated. f a c p 20. This terminal pipe extends Another-object of the invention is to furalong the bottom 10 of the tank A midway ther the effectiveness of the cooling of the between the sidewalls l1 and 12 thereof, said b i i ch a. cooling tank by arranging pipe being formed with a slot 21 in its upper i the, refrigerant coils to accord with th strueside extending practically throughout the enture and arrangement of the brine feed and tire length thereof. Thus slotted, said terreturn terminals. minal pipe 19 provides for the egress of fluid A further object is to dispose the elements from the tank A as will more fully herein- 3c of the cooler in such relation, that a connec after appear. The return main 17 depends tive and diffused circulation of the brine is in o the tank A near the endwall 14, the set up by the pump within the tank about the lower end of said main 1'? being fitted at the refrigerant coils, which circulation is augbottomof the tank with a T coupling 22 from mented by gravity. which issue two branch pipes 23 and 24.

With the foregoing and other objects in These branch pipes 23 and 24 are respectively 85 view, which will appear in the following desupplied with L fittings 25 and 26 into which scription, the invention resides in the novel brine return terminals 27' and 28 are respeccombination and arrangement of parts and tively threaded. Each of said terminals comin the details of construction hereinafter deprises a pipe slotted, as at 29, at the upper 40 scribed and claimed. side and longitudinally thereof, each pipe In the drawings, Fig. 1 is a view in plan being fitted with a cap 30 at the end thereof a brine cooler embodying my invention, of opposite its point of connection with its the cover of the tank being removed; Fig. 2 respective branch pipe. Like the terminal is a vertical, longitudinal sectional view of feed. pipe 19, the terminalreturn pipes 27 and the cooler, said view being taken on the line 28 extend along the bottom 10 of the tank A 22 of Fig. 1 and Fig. 3 is a vertical sectional from the endwall 13 to the endwall 14. VVithview taken on the line 3-3 of Fig. 2. in the tank A are two groups B and C of Reference being had to the accompanying elongated banked coils 31, the group B bedrawing, it will be seen that the illustrated ing disposed between the terminal feed pipe 55 embodiment of my invention includes an elon- 19 and the terminal return pipe 27, while the ad convective and difiused circulation of brine,

group C occupies position between said feed pipe 19 and the second terminal return pipe 28. These banked coils 31 are individually fed from beneath with a suitable refrigerant through a feed pipe 32 entering the tank through the bottom 10 thereof, said banks of coils 31 all being connected with a return pipe issuing through the sidewall 11 of said tank. The banks of coils 31in each group are uniformly spaced apartvertica-lly, said groups being spaced at greater distances from each other and from the acent sidewalls the tank A. That is tosa-y, the inner iked coils 31 of the two groupslB and C are relatively widely spaced apart to pro vide an unobstructed vertical space above the slot 21 in the terminalreturn pipelll, while the or r banked coils of said groups B C are relatively widely spaced respectively from the sidewalls-11 and 1:2 to provide unobstructed vertical spaces above the slots 29 in the terminal return pipes 27 and 28.

Brine or other fluid in the tank Aj-is reduced in temperatureby the refrigerant such as ammonia or the like passing through the Cells 31.

o The'cooled brine has egress from the lower portion of the tank A through the slotted terminal feed pipe 19, under the action ofthe usual pump incorporated in the feed main 16. Such pump, after propelling the brine througl the associated refrigerating system, forces the then warmed brine back to the tank A, said brine having ingress to said tank 3 through the slotted terminal return pipes 2'7 and 28. The upward introduction of brine at thelsides of the tank and the downward withdrawal of brine along the center thereabout the refrigerant Cells 81, which circulation is augmented by gravity. In this connection, it will be comprehended that the brine along the relatively warm sidewalls '11 and l2will rise, while the brine medially of the tank and remote from said sidewalls will descend underthe extreme cooling effect'experienc'ed between the two groups B and C of coils 31; Thus,jit will be understoodthat the circulation of brine within the tank A under the natural laws corresponds with the circulation thereof under the act1on of the pump of a'refri erating system, which circent to one sidewall of the tank and the other adjacent to the opposite sidewall, each of said terminal return pipes having a slot formed longitudinally thereof in its upper side, and two groups of elongated refrigerant coils lengthwise disposed longitudinally of. said tank within the same, said groups of coils being spread apart medially of the tank to provide a clearvertical space-above the slot in the terminal feed pipe and each of said groups'of coils being spaced from the sidewall of the tank nearest thereto to pro-- v'ide-aclear vertical space above the slot in the terminal return pipe adjacent to said sidewall.
